After I installed ArchLinux, I found there were no wifi i can connect, and got errors: your wireless card not opened
sudo rfkill list
output:
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
that Hard blocked: yes means your hardward wifi button off, pls set it on.
so strange, wifi is ok after i switch windows 10.
and i tried to press [Fn]+[F2], but problem persisted.
i guess it's a trouble of kernel module rfkill.
create a file named rfkill.conf in /etc/modprobe.d.
puts these content into it to prevent kernel loading rfkill
blacklist rfkill
reboot, then you can ride on the Internet with freedom.
refer to arch wireless network connection
